What Can Relace Do? Key Features
Repos
Relace's source control system is specifically designed for AI agents, featuring lightweight push/pull operations with no rate limits. The infrastructure supports fast branching for spawning subagents and automatic indexing for efficient two-stage retrieval. This makes it ideal for high-throughput coding operations where traditional source control systems might create bottlenecks.
Code Retrieval
Relace offers best-in-class semantic search that scales effortlessly to large codebases. With retrieval recall rates of 78.29% (outperforming competitors like Voyage Rerank at 60.84%), developers can quickly find relevant code segments across extensive repositories. The system uses built-in two-stage retrieval that enables 10x larger embed/rerank models for more accurate results.
Fast Apply
Relace's universal code merging model processes file edits at an industry-leading 10,000 tokens per second - significantly faster than competitors like Cerebras (3,300 tok/s) or OpenAI (85 tok/s). This smart merging capability ensures AI-generated edits integrate seamlessly with existing code, reducing merge conflicts and maintaining code quality.
Specialized Models
Relace develops purpose-built small language models (SLMs) that outperform frontier LLMs on specific coding tasks. These in-house trained models specialize in code retrieval, merging, and generation, offering better performance for autonomous code generation subtasks compared to general-purpose LLMs.
Low Latency Infrastructure
Relace's optimized inference stack delivers exceptionally fast response times, making it practical for real-world development workflows. The system is designed for production environments where code correctness and consistent results are critical, with execution times typically under 2 seconds for most operations.
Best Relace Use Cases & Applications
Automated Code Reviews
Engineering teams can use Relace to accelerate code review processes. The system can automatically analyze pull requests, suggest improvements, and even implement simple fixes at unprecedented speeds, reducing review cycles from hours to minutes.
CI/CD Pipeline Enhancement
Integrate Relace into continuous integration pipelines to automatically fix common issues, update dependencies, or implement security patches. The fast merging capability ensures these automated changes don't slow down deployment cycles.
Legacy Code Modernization
Teams working with legacy systems can use Relace's powerful retrieval and modification capabilities to gradually update and refactor old codebases. The semantic search helps developers understand complex legacy systems quickly.
AI Pair Programming
Developers can use Relace as an intelligent coding assistant that understands project context through the codebase retrieval system, providing more relevant suggestions than general-purpose coding assistants.
